Fig. 17 shows in perspective a heel block whichis to be operated upon by the illustrative machine;

Fig. 18 is a perspective view of the block illustrated in The illustrative machine is described with reference to trimming material from theupper face portion 30 (Fig.

' 17) of a wedge heel block 32 to form a partially trimmed heel block 32a (Fig. 18) having an upper or attaching face 34 a portion of which (outlined in phantom) is approximately complemental to the heel seat and shank portions 36, 38 respectively of a platform 40 (Figs. 20, 21 and 22) which has been stitched to the bottom of a lasted-full-fashioned shoe 42 and to which a heel 44,

turned from the block 32a and thereafter covered, is

subsequently secured. 'After the heel block 32ahas been formed by the use of the illustrative machine, material is trimmed from the side and rear faces of the block by the use of a wood heel turning machine (not shown) to produce the wedge heel 44.

The face 34 of the heel block 32a comprises a heel seat portion 39 which is slightly concave transversely and is also slightly concave longitudinally at its rear end, and which is defined by a margin 48 corresponding to a heel seat rim 5%) of the wood heel 44 and arranged approximately in a plane. The face 34 also includes a shank portion 52 which is separated from the heel seat portion 39 by a heel breast line 46 and is concave transversely and which is defined by an inner or instep margin or line 54 and an outer margin or line 58, said instep line 54 corresponding to an inner or instep edge or rim 56 of the heel 44, and said outer line 58 corresponding to an outer edge or rim 60 of a shank portion 61 of an upper or attaching face 62 of the heel, different portions of the inner or instep line 54 being higher than laterally opposed portions of said outer line 58. In the finished heel 44 diffe'rent portions of the rim or edge 56 of the shank portion 61 of the upper or attaching face 62 of the heel are higher than transversely opposite portions of the outer rim oredge 60 of said shank portion of the heel, said face 62 being shaped to form fit the heel seat and shank por tions 36, 38 of the bottom of the platform 44) of the fullfashioned shoe 42. Sides 63, 63a and 65, 65a of the blocks 32, 32a respectively from which material .is.

trimmed during the forming of the inner and outer sides of the heel 44 will be described as the inner and outer sides respectively of the heel blocks. 7

When the heel 44 is properly positioned upon and sewell as the rim 50 of a heel seat portion 71 of the face 62 of, the heel, hug the platform 46) which issconformed.

ae wa to the heel seat and shankportions of the bottom of the lasted shoe 42. The shank and heel seat portions 61,71 of the upper face 62 of the heel 44 are separated by a heel breast line 46a corresponding to the heel breast line 46.

The shank and heel seat portions 38, 36 respectively of the platforms 40 of full-fashioned shoes 42, which are of different sizes and styles and into which lasts 43 have been"slipped, are of different shapes audit is desirable that the upper faces 62 of the heels-shall be formedsubstantially complemental to said shank and heel seat portions of the platforms, thereby insuring that the heels shall merge gracefully with and shall effectively support the shoes. The longitudinal contour of the outer margin of the shank portion 38 of .thebott om of the platform 40 is generally similar to the longitudinal contour of a median line along said shank portion and the longitudinal contour of the inner or instep margin ofthe shank portion of the bottom of the platform 40 is raised somewhat with relation to a transverselyoppositefl portion of the outer shankportions 61 of the attaching faces 62 of heels 44,which are to be attached to full-fashioned platform shoes42 of different sizes and styles, shall be etfectively formed to shapes complemental to the shankportions38 of the bottoms of the platforms 40 of'the shoes, Ihave found :that itisdesirable, as the heel block 32 traversesiithe cutter 70 to formthe shank portion 52 of the attachingface 34 of the block 32a and accordingly the shank portion 61 of the attaching face 62-of the heel 44, to tilt the heel block 32,laterally away from the cutter about an axis 72 which extends generally lengthwise of and substantially along the outer margin of the shank portion of the attaching face being formed on the block. The illustrated machine is adapted quickly and effectively to form heel attaching faces 34 on heel blocks 32 which are of different lengths, widths, heights and/orpitches and from which form fittipg wedge heels 44 of different sizes and styles may beturned.

In order to form the attaching face34 upon the heel block 32to provide the partially completed block 32a, said block 32, secured to a carrier 64, which is journaled on a'yoke or mount 67 in turn journaled upon an adjusta'ble supporting slide or-bracket 69 *(Figs. 2 and 3), is

manually swung about two spaced parallel or vertical axes 66, 68to allow the heel block to traverse the rotary cutter 70, which has an axis73, in a predetermined. path controlled by means hereinafter described. The block 32 is held against lateral tilting as the heel seat portion 39 of its face is being formed but, as the shank portion 52 of its face is being formed, is tilted laterally about the hori-,

zontal axis 72 then extending generally lengthwise of and along the outer margin 58 of said shank portion. The line 58 is arranged in close proximity to a shank portion of an outeredge 74a of the face of the block 32a as whll as in close proximity to thepreviously existing shank portion of an outer edge 74 of the upper face portion 30 of the block 32 and accordingly the block 32 or 32a as it; traverses the'cutter 70 may be described as being tilted laterally about an axis extending generally lengthwise of the upper outer. corner portion of the block. T. i

Rotatably mounted in a bearingboss 76 (Fig. 1) of a main frame 78 of the machine and driven by an electric motor 80 secured to said frameisa vertical spindle-82i 4 The spindle 82 has a shoulder 84 (Figs. 1, 4 and 5) on which restsan interchangeable spacer 86 and clamped by a screw 89 between a lower clamping collar 88 which rests on the spacer 86, and an upper clamping collar 88a are a pair of cutting blades 90 having cutting edges 92 which are convex lengthwise and which, when the cutter is rotated, generate a barrel-shaped surface or locus 94. The cutting blades 90 which fit in grooves 96, 98 of the collars 88 88a respectively may be replaced by cutting blades 90 having edges 92 of different lengths and curvatures in accordance with the ,Widthof the heel block 132 to be operated upon and the desired transverse concave curvature of the face 34 of the heel block 32a.

Secured by screws 100 (Fig. 1) in different forward and rearward adjusted positions in a horizontal rectilinear guideway 102 of the main frame 78 is a lower abutment, rub plate or rub collar 104 (Figs. 1, 4 and 5) having a cylindrical face 106 vertical elements of which, when the machine is at rest, are coincident with vertical lines 108 respectively extending vertically through a maximum circumference 110 of the locus 94 of the cutting edges 92 of the cutter 70 which collectively may be referred to as a cutter head.

Secured in different operative positions in a rectilinear guidway 112 (Fig. 3) of a bracket 114 is an upper abutment, rub plate or rub collar 116 provided with slots 118 through which pass clamping screws 120 which are a threaded into the bracket and which, after the rub collar has been properly positioned in the bracket by the use of an adjusting screw 121, are screwed down to clamp the rub collar to hold it in its adjusted position in the guide,

way 112. .y

In order to allow the cutter head of the machine to be changed, it is desirable to move the rub collar 116 away from its operative or active position shown in Figs. 1, 3, 4 and 5 and accordingly the bracket 114 is fulcrumed on a pair of bearing screws 122 in the main frame 78. The bracket-114 has formedin it a slot 124 for receiving ascrew 126 which may be rotated into a position in which it permits the bracket to be swung from its horizontal active position to a raised,inactive position (not shown). After the bracket 114 has been swung into its active position against a stop face 148 of the main frame 78,

the screw 126 is rotated to its position shown in Fig. 3

to secure the bracket and accordingly the rub collar 116 in its active position. The upper rub collar 116, as in the case of the lower rub collar 104, isfso constructed and arranged that elements of a cylindrical face 130 I thereof are approximately coincident with the vertical lines 108 intersectingthe maximum circle of the locus, 94 which circle is includedin a horizontal plane 129 which may be described as the transverse median plane of the cutter. The cylindrical faces 106, 130 of the rub collars 104, 116 respectively may be defined as being arranged coaxially with or in concentric relation to the cutter 70 be forced against 'a concave surface 136 at the lower end of the spindle 82.

Movable along a vertical dovetail guideway 138 (Figs. 2 and 3) of the main frame 78 :of the machine is the adjustable supportingslide or bracket 69 into which is threaded an elongated screw 142 journaled in the main frame 78 and which has secured to it a bearing pin 144. Journaled upon the bearing pin 144,'which may be considered part of the supporting slide 69, for movement about the axis 68 and supportedupon a thrust bearing 1 46 (2) is a suspension or hearing block 148 having threaded into it a bearing stud 150 on which is secured by a not 152 a ball bearing 156. Mounted upon the ball bearing 156 is a coupling unit 160 which comprises a dovetail-guide 162-normally secured by interlocking means comprising retaining screws 164 to the yoke 67, said unit being retained on the bearing block by a ring 154 secured to and forming part of a housing 158 of said unit. The suspension block 148 and the yoke 67 may be referred to as a mount.

The housing 158 of the coupling unit 160 has formed in it a pair of horizontally disposed guideways 168 in which are mounted latches 170 having cylindrical ends 172 one of which at a time is active and, when it is desired rigidly to lock the housing to the bearing block 148, fits in a cylindrical bore 174 of a filler piece 176 fitting in a notch 178 of a forwardly projecting flange 180 of the block 148. When it is desired to tilt the coupling unit 160 and accordingly the yoke 67 to which said unit is secured about the axis 72 with reference to the bearing block 148, the filler piece 176 is removed from the notch 178, the cylindrical end 172 of the forward of the two latches 170 then being free to move slightly between upper and lower faces of the notch. With the above described construction the carrier 64 is permitted to swing, tilt or rock a few degrees in opposite directions about the axis 72, the swinging movement being limited by the engagement of the cylindrical end 172 of the forward latch 170 with upper and lower faces of the notch 178.

Threaded into the yoke 67 is a bearing stud 182 which fits in a stepped recess 184 (Figs. 3, 12 and 13) in the dovetail guide 162 and has a horizontal axis 186 which may be referred to as an adjusting axis and is usually ofiset a distance 187 (Fig. 12) above or below the axis 72 in accordance with the setting of the coupling unit 160 for right or left work, as will be explained later. The forward latch 170 is manually slid between an active position in which its cylindrical end 172 enters the bore 174 of the filler piece 176 or if the filler piece 176 is removed from the notch 178 enters the notch, and an inactive position in which the entire latch is retracted into its guideway 168,'by the use of a pin 188 which is secured to the latch and extends through a slot 190 (Figs. 2 and 13) formed in an adjacent portion of the housing 158. Each of the latches 170 is retained in its active and inactive positions along its guideway by a spring-pressed ball 192 slidingly mountedin the housing 158 and engaging in either one of two notches 194 in the latch.

Fixed to the dovetail guide 162 of the coupling unit 160 is a plate 196 in which is journaled an adjusting screw 198 threaded into the housing 158 of said unit to enable the dovetail guide and accordingly the bearing stud 182, to which the yoke 67 is secured, to be moved toward and away from the axis 72 of the bearing stud 150 in accordance with the width of the heel block 32 being operated upon, the distance 187 between the axes 186 and 72 being equal toone-half the width of the heel block 32 to be operated upon for reasons which will be apparent later. In order that the machine, adjusted for operating upon left work as illustrated in Figs. 5 and 12, may be adjusted. for operating upon rightwork for example, the retaining screws 164 are turned out of threaded bores 199 (Fig. 12) of the dovetail guide 162 and are withdrawn from said guide. The coupling unit 160 is then rotated counterclockwise, as viewed in Fig. 11, 180 aboutthe bearing stud 150 and accordingly about the axis 72, said unit carrying with it the yoke 67 which, because it has little tendency to rotate and is usually held by the operator, rides. upright, the axis 186 of the bearing stud 182 moving in a path 201 about the axis 72 as illustrated in Fig. 11. The retaining screws 164 are then threaded intov the opposed threaded bores 199 of the dovetail guide 162 to secure the yoke 67, in a lowered operating position, to the coupling unit 160. The coupling unit 160 may be described as being rotatable aboutthe tilt axis 72 to move the yoke 67 selectively between two ditferent operating positions in which the transfer axis 186 is positioned equal distances from and at diametrically opposite sides of the tilt axis. 7

1 The carrier 64 comprises an upper portion 200 upon which is pivotally mounted a work clamp 202 and to which is adjustably secured either a pattern 204 or a pattern 210, and a lower portion which has adjustably secured to it a work holder 208 and has secured to it in a fixed position either the pattern 204 or 210. The patterns 204, 210 are secured to the upper and lower portions 200, 206 respectively of the carrier 64, as illustrated in Fig. 4, when right work is being operated upon and the patterns 204, 210 are secured to the lower and upper portions'206, 200 of the carrier, as illustrated in Fig. 5,

when left work is being operated upon. The upper and lower portions 200, 206 of the carrier 64 are normally secured together by screws 212 (Fig. 1) which are threaded into the upper portion of the carrier and extend through an elongated slot 214 in the lower portion of the carrier, the upper portion of the carrier straddling and fitting in guideways 216 formed in the lower portion of the carrier. The upper portion 200 of the carrier 64 is provided with a scale 215 for use in adjusting the lower portion 206 of'the carrier heightwise relatively to said upper portion to accommodate heel blocks 32 which are of different widths as will be explained later.

Secured to and forming part of the upper portion 200 of the carrier 64 is a trunnion 218 which fits rotatably in :a bore 220 in the yoke 67 and has threaded onto it a nut 222, a thrust bearing 224 being interposed between the nut and the yoke. Secured to and forming part of the lower portion 206 ofthe carrier 64 is a trunnion 226 which fits rotatably in a bore 228 of the yoke 67 and has secured to its lower end by a clamp screw 230 a stop lug 232. The trunnion 218 has formed on it a scale 219 for use in centralizing, by turning the nut 222, the carrier 64 as an entirety in the yoke 67, said carrier being adjusted in the yoke lengthwise of the trunnions, which have the common axis 66, until a longitudinal median plane 221 of the block lies in the horizontal median plane 129 of the cutter 70. It will be noted that when the carrier 64 and the heel block 32 are centralized in the yoke 67 the axis 186, 'which may be described as the transfer axis, lies in the plane 221 of the heel block 32 secured in the carrier. The mount 67 may be described as being journaled for arcuate movement, that is movement in which all portions thereof move simultaneously through equal concentric arcs about the tilt axis 72 which is disposed at approximately right angles to the fixed axis 68 and is constrained for arcuate movement about said fixed axis. The swing axis 66 may be described as being fixed with relation to the mount 67 and as being constrained or journaled for arcuate movement about the,

tilt axis 72.

The yoke 67 is swung manually about the bearing pin 144 and accordingly about the axis 68 by the operator who grasps with his left hand a grip 223 (Fig. 2) which is mounted on a bracket 225 secured by screws 227 to the yoke. The carrier 64 is manually swung upon the yoke about the axis 66, which may be described as the carrier :axis, by the operator who grasps in his right hand a handle 233 (Figs. 1 and 2) which is secured by screws 235 to the lowerportion 206 of the carrier. By simul taneously moving the yoke 67 about the axis 68 and the carrier 64 about the axis 66, which is parallel to the axis 68 and shifts with the yoke, the heel block, positioned upon and secured to the carrier and guided, controlled or governed by the engagement'of the patterns 204, 210

with the rub collars, may be moved in a predetermined path past the cutter to form the face 34 on the heel block 32a. In order to relieve the operator the yoke 67 may be rotated about the axis 68 by fluid pressure means similar, for example, to that shown in the above-mentioned Patent No. 2,613,705. 7

Fulcrumed on a pin 234 secured to the upper portion 200 of the carrier 64 is a bell crank lever 236 having a lower arm grooved to receive the clamp 202 which may be secured in different adjusted positions to the arm by screws 238threaded into said arm and passing through 7 elongatedslots (not shown) in the clamp. Secured to th e upper portion200 of the'carrier64 is-a cylinder 240 in which isreciprocablea piston 241 formed integral with -a piston rod "242 operatively connected! to an upstanding arm of the bell crank lever 236. t The piston 242 is :urged against a stop (not shown) in one direction by-a spring,

air under pressure. being supplied to the cylinder through a piston rod 249 which is reciprocablein an air cylinder 1 251. Secured to the frame 78 'is"a stop 253 and surrounding the shaft 237 and having its opposite ends engaging the guard and the main frame 78 is a coil spring 255for constantly urging the guard clockwise, as viewed in Fig. 16,:until a shoulder 257 of the abutment 241 engages the. stop 253 to retain said guard in its masking position." When an is admitted under pressure through a line 259 to the cylinder 251, .the piston rod 249 moves to the right asviewed inFig. 16,-causing the guard 239 to be. swung counterclockwise with theshaft 237 until a shoulder 261 of the guard 239 engages the stop 253.

Compressednir is supplied through a line 263 (Fig. 1) to the valve 246 which is operated bya trigger 265 fulcrumed onthe valve and overlying the handle 233. As

the operatoripositions the heel block 32 in the holder 208 he grasps thehandle233 and depresses the trigger'265 thereby causing air under pressure to be admitted to the cylinders 240 :and 251 with the result that the clamp 202 retains the blocksecurely in the holder 208 and the guard 239 is swungcounterclockwise, as viewed in Fig. 16, to its inactive position from in front of the cutter'70.

The lower portion 206 of the carrier 64 comprises a platform 248 which is provided with a rectilinear channel 258 (Figs. 6 and 7) adapted to receive a depending flange of a plate 254.and has elongated slots 252, said plate being secured tothe platform'in different adjusted positions lengthwiseofthe channel by bolts 256 which pass through the slots and are: threaded into the plate.

The. upper rear portion of the plate 254 is rabbeted and zontally. Secured to the plate 254 is a vertically disposed bearing rod 264 having journaled on it a sectoral rest 266 which is slidably supported on the plate and may be set in different positions about the bearing rod by the use of a screw 268 which is threaded into theplate 254 and passes through an arcuate slot 270 formed in the rest. The sectoral rest 266 has a vertical flange 272 provided with horizontally disposed slots 274 (Figs. 2 and 6) through whichpass screws 276 (only one shown) threaded into a backing board 278 which maybe secured in different lengthwise positions along the rear face of said flange. Secured by screws 20 to the vertical flange 272 of the sectoral rest ,266 is a guide bar 282 in a recreetilinear guideway 284 of which is mounted a slide 285havinga slot 287 for, receiving ascrew 289 threaded into the guide bar and sefling .tos ec'ure the. slide to said bar.: The slide 285 has formed in its upper face a r ectilinea1 guideway 291 which is arranged at right angles to the guideway 284 and has adjustably secured to it by a screw 293 an end gage286e When the heel blocks 32 a e n w t pr eterm e s an a e t s t ar positionedlengthwise in --the holder 208 by engagement of their rear ends with the. gage, 286, which may be quickly and .efiec tiuely i ,set einztdifierent ipositions lengthwise .4 of

tlieguideway 284";by the use of ascale292 formed upon the vertical fiange 272 of .the sectoral rest 266.

The. heel block 32is supported in the machine, as best shown in: Figs. 1, 4, 5: and 6, on'e side of the block-rest ing upon the planar serrated upper face of the block suppo'rt262 andu'the tread or bottom face of the blockrestingragainst the backing board 278, the clamp 202 being forced against the. other side of the blockto hold said block in place.

' In order to insure against the carrier 64 being moved into engagement with the cutter because of the carrier being. swungon the yoke beyond predetermined limits, theamountof pivotal movement ofthe carrier about the axis..-66.is'limitediby mechanism which will now be describedl Secured by :screws 295 (Figs. 2 and .3) to the yoke, 67 is a: bracket 297having threadedthrough it. a

stop screw .299 which may be set in different adjusted of the carrier in said direction upon the yoke 67.

counterclockwise rotation, as .viewed in Fig. 3, of the carrier .64 on. the yoke 67 is limited by the engagement of the stop lug:232 with a shoulder305 ofthe yoke.

When thewedgeheel blocks 32 have been pretrirnmed or cut to'the'desired length theyare positioned lengthwise on the: holder 208 by gaging from their forward ends. Accordingly, the yoke 67 has secured to it by screws 294 (Figs. 2, 3 and '6) ,a post 296 upon which is mounted for vertical adjustment a block298having at its upper end a 'guideway 300 for a T-shapedsupport 302 slotted to receive a screw 304 threaded into the block. Threaded into the T.-shaped support 302 and extending throughan arcuate slot 306-in an end gage 308.are screws 310 which may be used to set. the end gage in the desired position uponjthe T-shapedsupport. It will benoted that the end gage 308 is secured to the yoke 67 and accordingly when said end gageis used to position the heel blocks lengthwise in the holder 208'the depending abutment 303 secured to the carrier 64 is held in engagement with the stop screw 299.

i In order to balance the yoke 67 so that it will be maintained yieldingly in an upright position but may be tilted about the axis 72 in response to the action of the patterns 204, 210 against the rub collars, there is secured by screws 312 to the yoke a bar 314 in an outer end of which is formed a notch 316. Secured by screws 318 (Fig; 3) to the bearing block 148 is a bar 320 through a bore in' an outer portion of which extends a screw 322 having threaded onto it a nut 323 supported bythe bar. To the lower end of the screw 322 is attached a spring 324 which carries a latch pin 326 (Fig. 2) shapedand arranged to be locked in the notch 316 so as yieldingly to support, through the bar 314, the yoke 67 in a substantially vertical or neutral position. Preparatory to setting up the machine, which is adjusted to operate upon left work for example, for operating upon right work, or vice versa, the latch pin 326 is removed from the notch 316, said pin being later inserted in said notch and the screw 322 being raised or lowered in the bar 320 sufiicientlyto apply to the bar 314 the desired amount ofbiasing force necessary to maintain the yoke 67 yieldingly in'its' vertical position. As above explained, in operating upon heel blocks 32 from which right heels 44are-to be formed the patterns 204, 210 are secured to the upper and lower portions 200, 206 respectively of the carrier, vas shown in Fig. 4, and in; operating upon blocks 32 from which left heels 44 are to' be formed the patterns 210, 204 are secured to the upper and lower portions 200,206 respectively of the carrier64.

;Fittingjin a vertical channel 328 in the upper portion 200 of the carrier 64 is an angle bracket 330 which :has

asvert cahslotafiftl (Fig.2). throughwhich passes .a screw 334' threaded into the carrier, said screw being loosened preparatory to adjusting the bracket to the desired height along the channel and being tightened to secure the bracket to the carrier. The patterns 204, 210 are formed to operate equal distances at opposite sides of heel blocks 32 of different widths and since the distance between the heel block support orledge 262 and the rabbet 344 is fixed, it will be apparent that the angle bracket 330 has to be initially raised or lowered into different adjusted positions in the channel 328 in accordance with the width of the heel block being operatedupon. The heightwise adjusted positions of the brackets 330 in the channel 328 for accommodating heel blocks 32 of different Widths may be readily determined by the use of a scale 331. The patterns 204, 210 also fit interchangeably in the rabbet 3440f the lower portion 206 of the carrier 64 and after being positioned lengthwise in the rabbet by alining the groove 338 or 338a formed on the patterns 204, 210 respectively with a groove (not shown) on the carrier 64, are secured to said lower portion of the carrier by a plate 346 clamped against the patterns by screws 348.

The patterns 204, 210 have laterally bowed rub collar engaging faces 352 (Fig. 9), 352a (Fig. 10), respectively comprising heel seat forming portions 356, 356a, Which have identical longitudinal contours, profiles or outlines, and shank forming portions 358, 358a which have different'longitudinal contours, profiles or outlines, the differences in said contours of said shank forming portions being best illustrated in Fig. 3 which shows the patterns in vertical alinement. The longitudinal contours of the patterns 204, 210 respectively vary in accordance with the sizes and styles of the heels which are to be formed from the heel blocks 32. In order that the rear end of the attaching face 34 of the heel block 32a shall be concave longitudinally, the faces 352, 352a, of the patterns 204, 210 are provided with run-in forming portions 360, 360a and in order that the heel block, after the forming of the forward end of the shank portion 52 of the attaching face 34, shall be guided away from the cutter in a controlled path, the faces 352, 352:: of the patterns are provided with run-off portions 362, 362a.

In view of the foregoing it will be apparent that during the forming of the heel seat portion 39 of the attaching face 34 of the heel block 32a there will not be any tilting of the carrier 64 about the axis 72 since the heel seat forming portions 356, 356a of the patterns 204, 210 are identical and in vertical alinernent and the cylindrical faces 130, 106 of the rub collars 116, 104 respectively are also in vertical alinement. In view of the fact, however, that the shank forming portions 358, 358a of the patterns 204, 210 have different profiles, the carrier 64 and aocordingly the heel block secured to it (assuming the machine is adjusted for right work as shown in Fig. 4), during the traversing of the heel block past the cutter and in response to'the action of the rub collars 114, 116 against the patterns 210, 204, respectively, swings counterclockwise about the axis 72 and away from the cutter to form the shank portion 34 on the heel block 32a. When the machine has been adjusted for left-work the patterns 210, 204 are secured to the upper and lower portions 200, 206, of the carrier, as shown in Fig. 5, instead of to the lower and upper portions of the carrier, as shown in Fig. 4, and the carrier swings clockwise as viewed in Fig. 5 about the axis 72 away from the cutter.

It will be noted that when the machine has been adjusted for operating upon right and left Work and is trimming material from the upper face .portion 30 of the block 32 the tilt axis 72, which is disposed at right angles to and intersects the axis 68, passes substantially through points of intersection of lines passing through portions or elements of simultaneous engagement of the patterns 204, 210 with opposing rub collars and an extension or plane of the outer side 65 of the heel block being trimmed. The carrier 64 may also be described as being tiltable about 10 an axis which is disposed at right angles to and intersects the axis 68 and which extends in, the vicinity of points of intersection of the plane of the block supporting ledge 262.

'32 is the uppermost side of theblock in the work holder 208 and in Fig. 5, which shows the machine operating upon left work, the outer side 65,0f the heel block is the lowermost side of the block which is secured to the work holder and rests upon the block support or. ledge 262 the work engaging portion of which may be described as lying in a plane.

In operating upon right work, as shown in Fig. 4, it is desirable that the uppermost face of the heel block (also the outer side 65 of the block) positioned in the holder 208 shall lie in the tilt axis 72 and in operating upon left work, as shown in Fig. 5, it is desirable that the lowermost face of the block 32 (also the outer side 65 of the block) positioned in the holder 208 shall lie in the tilt axis. In changing over from left to right work or from right to left work of the same width, it is necessary that the heel holder 208 and accordingly the heel block 32 secured to it shall be lowered or raised respectively the width of the heel block so that the outer side 65 or the plane of said face (the uppermost face of the heel in Fig. 4 and the lowermost face in Fig. 5) shall lie approximately in the axis 72. It is desirable that the coupling unit 160, in moving from one to another of its operating positions on the yoke 67 by swinging the bearing stud 182 180 about the tilt axis 72, shall move the yoke 67 lengthwise of the axis 68 (heightwise of the machine) a distance equal to the Width of the heel block 32. Accordingly, the screw 198 is initially rotated sufliciently to cause the transfer axis 186 to be raised or lowered relatively to the tilt axis 72 so that said transfer axis lies in the longitudinal heightwise median plane 221 of the block 32 positioned in the machine. When such adjustment has been effected the block 32 positioned and clamped in the holder 208 is raise-d or lowered the width of the heel block when the coupling unit is moved from one to the other of its operating positions on the yoke 67.

When the machine is to operate upon heel blocks 32 from which are to be formed heels (not shown) to be attached to slip lasted shoes, the bottoms of the platforms of which are flat transversely throughout their widths, said machine is provided with a cutter (not shown) hav ing straight cutting edges and a pair of patterns 364 which are identical and are secured to the upper and lower portions 200, 206 respectively of the carrier 64 in place of the patterns 204, 210. Preparatory to operating on this type of work, the filler piece 176 is inserted in the notch 178 of the bearing block 148 and the cylindrical end 172 of one ofthe latches is inserted in the bore 174 of the filler piece thus locking the coupling unit 160 to the bearing block 148 which is then rigidly secured to and may beconsidered part of the yoke 67.

Preparatory to operating upon heel blocks 32, which are of different lengths, heights, widths and/ or pitches and from which heels 44 are made to fit the heel seat and the shank portions 36, 38 of full fashioned shoes of.

various sizes and styles, various adjustments hereinafter explained have to be made in the machine.

It will be apparent that in order to form the attaching face 34 upon the heel block 32 said block must be positioned in the machine with its longitudinal heightwise median plane 221 in substantial coincidence with the transverserrnedian plane 129 of the cutter 70 and accordingly the plane of maximum circumference 110 of the locus 94 of the cutting edges 92 of the cutter 70. The patterns204, 210, as above stated, areprofiled on the premise that they are to be positioned equal distances at opposite sidesof the heelblock 32 positioned in the "*11 machine irrespectiveot the width of the: block audaccordingly .it is necessary to maintain this condition. Furthermore, the, plane of the outerface 65 f the-heel block 32 positioned in the machine must approximately include the axis 72, and the transferaxis 186 of the-bearingstud182 must lie substantially in the longitudinal heightwisemedian plane :221 of the 'heel block 321posi-z tioned in the machine, the distance between the tilt and the transfer axes 72, 82 being-equal to one-half the width of the heelblock. It is also desirable that'when the patterns 204, 2l0jare in engagement with opposing rub collars the tilt axis 72, which liesin the plane of the outer side 65 of the heel block, shall substantially inter sect the line 108 connecting vertical elements of the rub collars simultaneously engaged by thelpatterns. With the foregoing and other desirable requirements to be sansfied, the machine is initially adjusted as hereinafter de-v length) is moved to and set in its proper adjusted position on the angular rest, the above adjustments being readily efiected by the use of scales 366 (Fig. 6), 368 and 292 respectively.

The bolts. 212 are then loosened and the lower portion 206 of the carrier 64 israised or lowered lengthwise of;

the axes 66, 68 in accordance with the width of the heel block 32 to be accommodated, the proper adjustment being readily effected by the use of the scale 215. When the bolts 212'have been tightened to secure the upper and lower portions 200, 206 of the carrier 64 together, the work supporting ledge 262 is so positioned that the will include the tilt axis 72. It will thenbe necessary to rotatethe elongated screw 142 to move lengthwise of the axes 66, 68 (heightwise of the machine) the entire work carrying assembling so as to move the transfer axis 186 substantially into the transverse median plane 129 ofthe cutter 70."

As above stated, the patterns 204, 210 used in operating upon the particular heel block 32 on hand are so shaped and arranged and so positioned and clamped in the carrier 64 that when they are in engagement with opposed rub collars, the axis 72, which lies in the plane of the outer side 65 of the heel block 32, extends in close proximity to the line 108 and accordingly extends generally lengthwiseof the heel block in the vicinity of the outer upper portion of the block being trimmed.

lnthe event that the machine has been operating upon left work (Fig. 5), the coupling unit 160 being secured to the yoke 64 in one of its two operating positions as heel block 32 to be operated upon and positioned in the x carrier is centralized Widthwise in said carrier. The nut 222 is next rotated to-raise or lower with relation to the yoke 67 the carrier 64 as anentirety lengthwise ofthe axes 66, 68 one-half the distance (determined by reading the scale 219 with reference to a shoulder 350 on said yoke) that the lower portion 206 of the carrier was raised or lowered with relation to said upper portion of the carrier but in an opposite direction. The upper properly lengthwise of the axes 66, 68 withjrelationto the yoke 64 for operating upon the particular work on hand, the transfer axis 186 being'included in the longitu dinal heightwise median plane 221 of the heel block 32 positioned in the machine. I

It will be apparent that when a heel block 32 ofa different width from that of the heel block just operated upon is centralized widthwise in the carrier 64 and the carrier has been centralized in theyoke 67 lengthwise of the axes 66, 68 of the plane of the outer face 65 of the heel block 32 lies above orbelowthe axis 72. When this condition exists, and assuming that the machine has been operating upon right work, and that right work is again to be operated upon,: the screw 198 is rotated to a position readily determined by the use of a scale 3 74 (Fig.2) so' that the distance 187 between the tilt axis 72 and the transfer axis 186 is equal to one-half the'width of the heel block 32 to be operatedupon' thereby moving the carrier 64 into suchaposition that when the particular heel .block is positioned in the-carrier its -outer-side*-65 tilting movement of the coupling unit 160 and accordshown in Fig. 12, and it is desired to operate upon right work of the same size and style, the operator, after removing the retaining screws 164 from the bores 199 of the dove-tail guide 162 of the coupling unit 160 and re-' moving the latch pin 326 from the notch 316, rotates the coupling unit 180 about the bearing stud and accordingly about the axis 72 as shown in Fig. 11. Such action causes the yoke 67, which remains upright during the changeover, to be lowered the width of the heel block 32 to be operated upon thereby moving the carrier 6.4 into such a position that the plane of the outer face 65 (then the uppermost face of the block as shown in Fig. 4) of the heel block 32 to be operated uponand secured to the carrier will substantially include the axis 72. The coupling unit is then secured to the yoke 67 in the other operating position upside down from that shown in Fig. 12, the retaining screws164 being threadediuto opposite bores 199 of the dove-tail guide 162 to secure the yoke 67 to the coupling unit. The latch 170, which has been rendered active by reason of the coupling unit 160 having been rotated 1180 about the bearing stud 150, is then slid into such a position that its cylindrical face 172 extends intothenotch 178 to limit ingly the ,yoke 67 about the axis 72. The elongated screw 142 is then rotated to a position determined by a scale 376 (Fig. 2) to raise lengthwise of the .axes 66, 6 8the adjustable supporting slide or bracket 69 and accordingly, the entire carriage assembly comprisingthe coupling unit 7160, the .yoke 67 and the carrier 64 until the longitudinal heightwise median plane 221 of the heel block 32 which is to be operated upon willbe coineident with the transverse medianplane 1290f the rotary cutter 70. The screw 322 which yieldingly supports the latch pin 326 is then lowered sufficiently to enable said latch pin to be'inserteddn the notch "316 and the spring 324 to exert on the yoke a biasing effect sufiicient to maintain the yoke, whenkthe machine is notin .use, in a substantially vertical position in which the cylindrical end 172 of the latch in the notch 178 is spaced from the sides of the notch.

When the heel block 32 to be operated upon is positioned upon and secured to ,the carrier 64 the axis 72 lies in the general plan'eof the upper side 65 (the uppermost face as shown in Fig. 4) ofthe heel block 34 and the transfer axis 186 of the bearing stud 150lies substantially in the longitudinal heightwise median plane 221 of the heel block.

After the necessary adjustments have been it made in the machine to accommodate the heel block 32 from which the heel 44 is to be formed, the operator places his right hand grips the handle. 233 and presses the tr gger I 265 .causing the clamp 202, acted on ,by the pneumatic pressure means above described, to be forced against the heel block to secure said block inplace in the carrier 64. The operator, while maintaining his hold on the handle 233 and maintaining the trigger 265 depressed, grasps the grip 223 of the bracket 225 with his left hand and swings the carrier 64 simultaneously about the axes 66,68 causing the exposed upper face portion 30 of the heel block 32 in the carrier 64 to traverse the cutter 70 in a path determined by the sliding engagement of the patterns 204, 210 with the rub collars, the trimming cut starting at the rear end portion of the block and progressing to the forward end of said block, thereby providing the heel block 32 with the attaching face 34. The operator then swings the yoke 67 away from the rotary cutter 70 and after releasing the trigger 265 to' render the clamp 24%2 inactiveremoves the block 32afrom the machine, 1 7
